First Test Drives on New Prague Trolleybus Route Na Knížecí – U Waltrovky

Prague continues to focus on environmentally friendly mobility: the first test drives on the new Na Knížecí – U Waltrovky route were successful, and the new electrified route is scheduled to begin operation in spring 2026.

The expansion of electrified public transport in Prague is progressing further. In addition to new tram lines, the city is increasingly investing in trolleybuses. Prague Public Transport (DPP) has now begun test drives on the current bus route 137.
